JIRA: https://jira.spring.io/browse/INT-3978 Previously the `MessageHistory.write()` always used `MessageBuilder` to populated the `history` header. Since the `MessageBuilder` doesn't care about the `source` message type, we might lose some important information, like `AdviceMessage.inputMessage` * Add conditional logic into the `MessageHistory` for all known `Message<?>` implementations * Provide appropriate tests in the `MessageHistoryTests` for known `Message<?>` implementations * Make `AdviceMessage` generic and fix all affected code on the matter * Since `MutableMessage` is public already, fix `MongoDbMessageStore.DBObjectToMutableMessageConverter` to use `MutableMessage` type directly. Add WARN for non-standard `Message` type
Spring Integration 
Checking out and Building
To check out the project and build from source, do the following:
git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build
NOTE: While Spring Integration runs with Java SE 6 or higher, a Java 8 compiler is required to build the project.
If you encounter out of memory errors during the build, increase available heap and permgen for Gradle:
GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'
To build and install jars into your local Maven cache:
./gradlew install
To build api Javadoc (results will be in build/api):
./gradlew api
To build reference documentation (results will be in build/reference):
./gradlew reference
To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)
./gradlew dist
Using Eclipse
To generate Eclipse metadata (.classpath and .project files), do the following:
./gradlew eclipse
Once complete, you may then import the projects into Eclipse as usual:
File -> Import -> Existing projects into workspace
Browse to the 'spring-integration' root directory. All projects should import free of errors.
Using IntelliJ IDEA
To generate IDEA metadata (.iml and .ipr files), do the following:
./gradlew idea
